i did it...now i have internet from my pc via bluetooth...thanks for that, but there are some weird things...
1) i can get connected in opera, but for example, if i want to download an image, the opera browser must end (or be minimized) in order to the mobile built in browser connect and save that picture...i wonder if opera can save images without having to be minimized (i've already seen the "Save Images" in Opera's tutorial homepage and it just won't work...)
2) only opera works with this kind of internet connection (PC >> bluetooth >> mobile)? i've tried to connect the mobile built in web browser, but it says "connection failure"...the same thing with gmail app. (in order to connect gmail or the Sony Ericsson built in browser, i've to connect normally to the internet (mobile >> MyCompany))
